Durango vs Expedition vs EnvoyXL

All,

Time to consider a new TV. We have a 2005 3023 that we pull with a '05 Grand Caravan with tow package. We're thinking about the big trip out west and the GC isn't going to cut it. Currently looking at either a Durango or Expedition. I just wanted to see if anyone is towing with either one of these vehicles and what your thoughts are. Also, if you have a Durango, do you have the 4.7 V8 or the "Hemi"? Also have given some thought to a GMC Envoy XL and XUV. Thoughts?

All feedback welcomed.

Thanks!
